ed certain new and useful Improvements in Hings and Brace-Bars for Folding Frames, of w ch the following is a specification.

lThe invention relates to hinges provided With a brace bar for connecting folding frames for transparent wind-shields for automobiles and the like; and the object of the improvements is to provide a frame composed of a lower and an upper member with a hinge and pivoted brace-bar'adapted to support the up er member andA allow it to be extended or fo ded upon the lower member, which is assumed to be stationarily mounted upon the vehicle.

I have attained this object in the frame With hinge and brace-bar constructed as illus- `trated in the accompanying drawings, in

which- Figure 1 is an elevation in perspective of a structure embod g the invention. Fig 2 is an elevation s owing an edge view of the frame extended. Fi 3 1s an elevation showing that side of t e frame to which the hinge brace-bar is applied, the frame being extended. -Fig. 4 is an elevation showing the edge of the frame folded. Fig. 5 is a detail showing in perspective a fra ment of parts of the frame structure at t e hinge junction in apposition. Fig. 6 is a detail showing the same parts as seen in Fig. 5 and an additional part in conjunction.

l i In the drawings the numeral 1 designates Athe outer members of the frame, and 2 the meeting members, which are made of wood ,j and bound on the outer edge with a metallic Vstrip 3. The inner edge is provided with a groove, into which the glass may be slid previous to the application of the meeting members. A groove 4 of the meeting member fits upon atongue 4a of the outer member and is 'held by means ofv a screw, as seen in Figs. 5, 6.

l The hinge and brace-bar as applied tothe frame arel lainly shown in Figs. 1, 2, 3, and 4 of the ravving The hinge comprises leaves 5 5, having the knuckle at 5b. The

l part 5 is provided with a pin at 6, which is of the requisite len th to extend through the frame-pieceY 1 an receive the perforated end ofthe brace-bar 7, which is secured on.the pin by means of a nut 6a, so as to turn on'the pin. The part 5a is provided with a threaded perforation at 6", which corresponds in position with a perforation through the frame-piece, and the opposite end of the brace-bar has a like perforation at 6, in which a thumb-screw 8 is applied to clamp the brace-bar against the opposite side of the frame-piece from the hinge when the frame is extended, as seen in Fig. 2.

The upper or folding member of the frame lies counter to the leaves of the hinge and is clamped to the frame-piece across the folding joint, so as to cooperate with the hinge' in forming a rigid support adapted to sustain the upper member of the frame against the air-pressure produced thereon by the movement of the vehicle.

Braces 10, connected with the hinge-pin at the top and with the vehicle-frame at the bottom, serve to support the lower member of the frame upon the vehicle.

What I claim isl. The hinge comprising pivoted leaves, ono of the leaves having a projecting pin and the other a threaded opening, in combination with a brace-bar pivoted at one end to the projecting pin of the hinge-leaf and having a perforation at the opposite end for a thumbscrew, as specified.

2. The combination with the folding :frame having opposite members each provided with a perforation, of a hin e having one member provided with a threa ed perforation and the 'other with a projecting pin adapted to the perforations of the frame; a

brace-barvpivoted at one end tosaid project- .1

lng pin and-provided with a perforation at the opposite end, and a thumb-screw fitted to the perforation of the brace-bar and adapted to engage the threaded perforation of the hinge, as specified.

3. The combination with the folding frame having opposite members respectively, provided with perforations and one member 1,05 I' j aving a projecting nut, of a hinge provided"k J v With a threaded perforation and a pin, a, ed

brace-bar pivoted to the pin, and provided with a perforation adapted to turn' into reg perforation of the -hiuge orthe projecting nut, as'speoied.
